Abstract
Purpose
The Multinational Association of Supportive Care in Cancer (MASCC) developed the MASCC antiemesis tool (MAT) as a tool for chemotherapy-induced nausea and vomiting (CINV) assessment and subsequently published its Japanese version in 2010. We evaluated the validity of CINV assessment in outpatients using the Japanese version of MAT.
Methods
Patients administered highly or moderately emetogenic chemotherapy in the outpatient chemotherapy unit of our hospital were included in the study. The study was designed as a prospective two-period crossover observational study to evaluate the correlation between the daily patient diary and the Japanese version of MAT in terms of CINV onset. We examined with a focus on reliability of the Japanese version of MAT particularly in the description of the delayed phase of nausea and vomiting.
Results
Patient descriptions of CINV onset in a total of 116 cycles in 58 patients (two cycles/patient) were analyzed. The CINV incidence indicated by the patient diary was similar to that by the Japanese version of MAT. The concordance rate between the two tools in the same patients was 86.2 % for CINV onset in the delayed phase. The nausea score was also similar between the two tools regarding the mean and variance, showing a strong correlation with a correlation coefficient of 0.71.
Conclusions
The results of the study showed that the Japanese version of MAT is a highly reliable tool for CINV assessment, indicating that it is valid for assessing CINV in outpatients.
